Slug (railroad)
In railroading, a slug is a version of a diesel-electric locomotive which lacks a prime mover, and often a cab. It derives the electrical power needed to operate its traction motors and motor controls from a fully-powered mother locomotive. When coupled together it takes advantage of the excess current that the mother's diesel-electric locomotive produces at low speed, providing additional horsepower and braking at such operation without the expense of a full locomotive. A slug is distinct from a B–unit, which has both a prime mover and traction motors but no cab. A slug may retain an operator's cab to allow engineers to operate a train with the slug in the lead, or may have the cab and much of the body removed to save space and allow the operator in the mother better rear visibility. Basic principles A slug is used to increase adhesive weight, allowing full power to be applied at a lower speed, thus allowing a higher maximum tractive effort. They are often used in low-s ...

EMD GP30
The EMD GP30 is a four-axle diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange, Illinois between July 1961 and November 1963. A total of 948 units were built for railroads in the United States and Canada (2 only), including 40 cabless B units for the Union Pacific Railroad. It was the first so-called "second generation" EMD diesel locomotive, and was produced in response to increased competition by a new entrant, General Electric's U25B, which was released roughly at the same time as the GP30. The GP30 is easily recognizable due to its high profile and stepped cab roof, unique among American locomotives. A number are still in service today in original or rebuilt form. History Development The GP30 was conceived out of the necessity of matching new competitor GE's U25B. The U25B offered while EMD's GP20 and its 567D2 prime mover was only rated at . The U25B also featured a sealed, airtight long hood with a single inertial air intake fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD40-2
The EMD SD40-2 is a C-C diesel-electric locomotive built by EMD from 1972 to 1989. The SD40-2 was introduced in January 1972 as part of EMD's '' Dash 2'' series, competing against the GE U30C and the ALCO Century 630. Although higher-horsepower locomotives were available, including EMD's own SD45-2, the reliability and versatility of the SD40-2 made it one of the best-selling models in EMD's history, edged only by the GP9, and the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental DDA40X. Peak production of the SD40-2 was in the mid-1970s. Sales of the SD40-2 began to diminish after 1981 due to the oil crisis, increased competition from GE's Dash-7 series and the introduction of the EMD SD50, which was available concurrently to late SD40-2 production. The last SD40-2 delivered to a United States railroad was built in July 1984, with pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD Dash 2
The EMD Dash 2 is a line of diesel-electric locomotives introduced by General Motors' Electro-Motive Division (EMD) on January 1, 1972. Designations of these models were those of the former models with "-2" added (e.g., the SD40 was replaced by the SD40-2). They retained the basic specifications of the earlier models in terms of power output and most other features, but introduced a number of improvements to the locomotives' internal systems, specifically the electrical systems and the trucks of the locomotives. These were intended to improve availability, efficiency, and ease of maintenance. One major improvement was a modularized electrical control cabinet, allowing maintenance by unit replacement and the use of common parts. These concepts were first tested on the DDA40X. Changes Minor externally visible changes common across the whole line include the following: * Modified trucks with damping struts. Four-axle trucks have damping struts on two diagonally opposite corners. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GE U36B
The GE U36B was a four-axle B-B diesel-electric locomotive produced by General Electric from 1969 to 1974. It was primarily used by the Seaboard Coast Line Railroad and its successors, although thirteen provided the power for the original ''Auto Train''. The U36B was the last GE high-horsepower universal series locomotive. Design General Electric's "high-horsepower" universal series locomotives were built around improvements to the 16-cylinder GE FDL-16 prime mover. The U36B, rated at , was the most powerful of the four-axle universal series and the last such design. It was visually indistinguishable from the GE U33B, both of which were long. The locomotives rode on Blomberg trucks from traded-in EMD general-purpose (GP) locomotives. Each locomotive weighed . In common with other high-horsepower locomotives of its generation the U36B had large "bat-wing" radiators at the rear. The Seaboard locomotives had an 81:22 gear ratio, permitting a maximum speed of . The U36B and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seaboard Coast Line Railroad
The Seaboard Coast Line Railroad was a Class I railroad company operating in the Southeastern United States beginning in 1967. Its passenger operations were taken over by Amtrak in 1971. Eventually, the railroad was merged with its affiliate lines to create the Seaboard System in 1983. At the end of 1970, SCL operated 9,230 miles of railroad, not including A&WP-Clinchfield-CN&L-GM-Georgia-L&N-Carrollton; that year it reported 31,293 million ton-miles of revenue freight and 512 million passenger-miles. History The Seaboard Coast Line emerged on July 1, 1967, following the merger of the Seaboard Air Line Railroad with the Atlantic Coast Line Railroad. The combined system totaled , the eighth largest in the United States at the time. The railroad had $1.2 billion in assets and revenue with a 54% market share of rail service in the Southeast, facing competition primarily from the Southern. The seemingly redundant name resulted from the longstanding short-form names of these two m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GE U25B
The GE U25B was General Electric's first independent entry into the United States domestic road switcher diesel-electric locomotive railroad market for heavy production road locomotives since 1936. From 1940 through 1953, GE participated in a design, production, and marketing consortium (Alco-GE) for diesel-electric locomotives with the American Locomotive Company. In 1956 the GE Universal Series of diesel locomotives was founded for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium agreement with Alco. History The U25B (nicknamed ''U-Boat'') was the first commercially successful domestic diesel electric road locomotive designed, built, and sold by General Electric after its split with the American Locomotive Company (Alco), a company dating back to the steam era. GE had developed internal combustion-electric generating, control, and drive systems in the early 1920s, which provided the foundation for the use of intern ...

Southern Pacific Railroad
The Southern Pacific (or Espee from the railroad initials- SP) was an American Class I railroad network that existed from 1865 to 1996 and operated largely in the Western United States. The system was operated by various companies under the names Southern Pacific Railroad, Southern Pacific Company and Southern Pacific Transportation Company. The original Southern Pacific began in 1865 as a land holding company. The last incarnation of the Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system. The Southern Pacific Transportation Company was acquired in 1996 by the Union Pacific Corporation and merged with their Union Pacific Railroad. The Southern Pacific legacy founded hospitals in San Francisco, Tucson, and Houston. In the 1970s, it also founded a telecommunications network with a state-of-the-art microwave and fiber optic backbone. This telecommunications network became part of Sprint, a compa ...

Radiator
Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in cars, buildings, and electronics. A radiator is always a source of heat to its environment, although this may be for either the purpose of heating this environment, or for cooling the fluid or coolant supplied to it, as for automotive engine cooling and HVAC dry cooling towers. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation. History The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, having received a radiator patent in 1857, but American Joseph Nason developed a primitive radiator in 1841 and received a number of U.S. patents for hot water and steam heating. ...
